Single-row angular contact ball bearings are self-retaining units with solid inner and outer rings and ball and cage assemblies with polyamide, sheet metal or brass cages. The raceways of the inner and outer rings are offset from each other along the bearing axis. The bearings are available in open and sealed designs. Their angular adjustment facility is very limited.

Double-row angular contact ball bearings can support axial loads in both directions and high radial loads. They are particularly suitable for bearing arrangements in which rigid axial guidance is required.
